AUTOMATIC WEIGHING AND PACKAGE-FILLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 532,036, dated January8, 1895.

Application filed March 12,1 8 94.

To all whom it may concern.-

Be it known that we, WILLIAM H. DoELE and EDWARD l-I. DEWSON, J r.,citizens of the United States, residing at Quincy, in the county ofNorfolk and Commonwealth of Massachusetts, have invented a new anduseful Improvement in Automatic lVeighing and Package-Filling Machines,of which the following is a specification, reference being had to theaccompanying drawings.

Our invention relates to a machine for weighing package goods, and hasmore particular reference to the feed and automatic cut off.

I 5 Our invention consists inan electrically operated automatic cut offwhereby the supply of goods from the feeder may be shut off as soon as apredetermined quantity has been fed to the receptacle on the scales, andin a feeding device which is automatically thrown out of gear at thesame time the feed is cut off, as will be more particularly describedand claimed. It is especially adapted for use in putting up driedCurrants and other sticky 2 5 goods, but may be usedequally well withdry goods.

In the drawings, Figure 1 is a side elevation of a machine embodyingourinvention. Figs. 2 and 2 are plan views partly in section with theconnecting wires shown in diagram. The parts shown in Fig. 2 are, in themachine, directly underneath the parts shown in Fig. 2, but are in thedrawings shown at one side for clearness. Fig. 3 is a detail view of thepackage holder. Fig. 4 is a longitudinal section on line 4 4 of Fig. 2.Fig. 5 is a rear end View of the scale portion, partly in section, online 5 5 of Figs. 1 and 2, the box holder B on the scale pan beingremoved.

0 Fig. 6 is a rear View of the scale beam (all dependent parts beingremoved), the scale beam support, and a section of the base on line 6 6of Figs. 1 and 2. Fig. 7 is a rear end View on an enlarged scale, andFig. 8 is a front end View on an enlarged scale.

A represents the feed hopper; B, the platform of a set of scales; B, aguard to hold the carton or package 0 in an upright position, and O afunnel inserted in the top of Serial No. 503,225. (No model.)

the carton to guide the goods from the outlet of the hopper.

The drawings represent the machine as it appears just as an empty cartonis being inserted in the holder on the scale, before it is pushed backfully into position, and before the slide which closes the outlet of thehopper has been opened.

E is the base of the scales. The scale beam D branches forwardly intotwo arms (Z d which are united again at the end. These arms have knifeedge pivots d d by which the beam is pivoted in the forked standard Emounted on the base E.

The platform B is formed with a downwardly extending stem b fastened tothe forked casting b which is suspended from the scale beam by the knifeedges b. The bracket casting b has a stem 1) pivoted at its lower end toa link 11 which in turn is pivoted to the stem (Z fixed to the standardE, thereby 7o maintaining the platform constantly in a horizontalposition as it rises and falls. The upwardly projecting part of the baseE forms a stop for the scale pan in its downward movement. 5

A linger-f is pivoted to the platform and its upper end projects throughan opening in the wall of the guard B before the cartonispushed backinto place, and itis held there byaspring f as shown in Figs. 1 and 3.The finger is slotted near its lower end, and a rod f pivoted on thesame pin f as the tingerfpasses through the slot f in the finger andstands at a slight inclination as shown, before the carton is inserted.This slot f should be large enough to allow a little play to the rod f\Vhen the carton is inserted, it pushes back the inwardly projecting endof the finger fand the spring f, and the rod f drops until an insulatedcross stud f strikes on the 0 metal contact posts 9 g as shown in Figs.1 and 2, making the electrical connection by which the slide gatecovering the outlet of the hopper is opened as will be hereinafterdescribed. 5

G is the weight.

The post 9 serves as a stop for the scale beam in its descent. Pivotedin the insulating forked end of the scale beam is a contact block (1 Aplatform H has secured to its top the contact terminal h and the springterminal h insulated from each other, the spring h being secured to thetable by the binding screw 7L2. The terminals h and h are so adjustedthat when the scale beam tips, the contact block (1 will come in contactwith them.

L L are two solenoids having shafts or cores Z Z whose adjacent ends arescrewed into the connecting block 1*. A slide gate K which controls theoutlet of the hopper has a threaded stem 76' which is screwed into theend of the shaft land reciprocates with the shaft. The size of theoutlet of the hopper may be regulated by the adjustable plate j andadjusting screw j. The slide passes over the friction roller 2' and rubsup against a sponge or wiper m held in the inverted cup m which shouldalways be kept moist, to clean the gate from any gum that may adhere toit from contact with the currants or other goods being put up. N N arethe sides of the supporting frame, connected with the hopper A. A link nis pivoted to the block Z and projects through an opening in the sideNot the frame. At its outer end it is pivoted to the lever n which isfulcrumed in the bracket of. The lever 11 has forked ends 12 71. whichhave pins sliding in a groove in the clutch O. This clutch is keyed tothe driving shaft upon which it is free to move laterally and is adaptedto engage with a clutch p on the hub of the small pinion wheel 19mounted on shaft 19 Pinion 19 engages with the large pinion P carried onshaft 19 Shaft 17 has a number of radiating pins 1 which serve as afeeder during the operation of the machine.

The wire 3 leading from any electric system connects by means of wires 8and s with one of the terminals of each solenoid. The wire 25 connectsthe other pole of the outside system with the other terminals of thesolenoids through connections as hereinafter described. Solenoid Lconnects with wiret through wire i contact post g, cross stud 1, contactpost g wire '6, contact post v contact bar 12 contact post e and wire tSolenoid L connects with wire t through wire 25, contact terminal h,contact block d spring terminal h, binding post k and wire i The bentlever o pivoted to the frame N at 11 carries in its upper end theadjustable striking point if, and at its other end an insulated contactbar 12 which is adapted to make connection between the two contacts oand 0 Before the carton is pushed into place so as to thrust back thefinger f and drop the rod j no current passes through either coil, theslide gate being closed and the clutch disengaged so that the feeder isnot in motion. As soon as the carton is pushed into place, the fingerfisthrust back, rod f drops until the cross stud f strikes the posts g gcompleting the circuit through the coil L and the cores Z Z are drawnback, opening the slide gate K and allowing the goods to pass down intothe carton. The clutch O and pinion p are brought into engagementthrough the link a and lever n, and the shaft 19 carrying the feeder isset in rotation.

In completing its backward stroke, the core Z comes in contact with thestriking point throwing the same backward and lifting the other end oflever 12 and contact 1: thereby opening the circuit in solenoid L atpoints '0 and n lVhen the carton is filled with the quantity for whichthe weight G is set, the scale beam will tip; and as the scale platformB begins its downward movement, the rod f comes in contact with thefixed end of the post X which then becomes the fulcrum of the rod f andthe cross stud f is lifted from the contacts g 9, opening the circuit ofsolenoid L at those points.

The post X should not be so high as to prevent cross stud f from makingcontact with posts g 9 before the beam begins to tip, but should be highenough to form a fulcrum for the beam and lift the cross stud f fromcontact as soon as the beam does begin to tip. The object of breakingthe circuit at this point is that it may not be re-established throughthe falling of contact bar 12 as core L moves away from striking point22 of lever o.

Contact block (1 coming into contact with the terminals h and hcompletes the circuit through the coil L and causes the core Z to bethrust forward to close the gate, throw the clutch out of engagement andto stop the feeder. When the carton is removed from the scales, thespring f will press the finger f forward again, picking up the rod f andthe weight G will carry down the scale beam and the contact block (1breaking the circuit through solenoid L. The gate will remain closeduntil a new carton is inserted and the circuit re-established throughcoil L by the dropping of rod f as before What we claim as our inventionis-- 1.
